IMPROVEMENT IN RICE-CLEANING MACHINES.

Specification forming part of Letters Patent No. 161,281, dated March23, 1875; application filed January 29, 1875.

To all whom it may concern:

Be it known that I, JOHN B. RUPERT, a resident of the city of NewOrleans and State of Louisiana, have invented a certain new and usefulImprovement in Rice Cleaning Machines; and I do hereby declare thefollowing to be a full, clear, and correct description of the same,reference being had to the annexed drawing making a part of thisspecification.

My invention has for its object the separation and removal from roughrice ot' the beard, dirt, and trash usually adhering to the same, inorder that the hulling of the said rice may be much more thorough andeffectual.

My invention will be more clearly understood by referring to thedrawing, in which Figure 1 represents a plan or top view of my improvedmachine; and Fig. 2, a vertical section of the same, the bisection beingthrough the line as w of Fig. 1.

My invention consists of an upright cylin der, A, which is provided uponits inner surface or periphery with corrugations, as shown at a a, 8:0.The outer shell of the cylinder A may be made of wooden staves bandedtogether, or of sheet metal, while the inner corrugated surface may beconstructed of a separate sheet of metal, or the entire shell of thecylinder may be constructed of cast-iron in one piece, as may be foundmore expedient. The cylinder A is provided at its lower end with a head,12, in the center of which is a air-- cular opening, a, the object ofwhich is to prevent an accumulation of grain or dirt beneath therevolving disk cl. Secured to the bottom of the cylinder is a brace, B,in the center of which is stepped an upright shaft, 0, Which is the axlefor the heaters O and spiral screwplate 0, which, in their rapidrotations, eifected by means of hand, animal, or steam power, applied toa pulley upon the upper extremity, subserves the important purposes ofdeflecting the grain contained within the cylinder A upwardly andagainst the interior corrugated sides thereof, and thereby thoroughlyagitating the grain until its outer covering or hulls are entirely freedof all foreign matter, when it is discharged through an opening, D, inthe bottom of the cylinder by withdrawing a valve, (not necessarilyshown,) and conveyed by any suitable means to a fanning apparatus, whereit is finally relieved of all dust and made ready for the hullingprocess.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

The cylinder A, provided with corrugations a a, and head I), shaft 0,heaters G, spiral screw-plate e, and brace B, all arranged as hereindescribed, and for the purpose specified.
